To @ZZ whom t may concern.:

Be it known that I, SEVERIN F. JnNsvoLD, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Scai'fold Brackets,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to scaffold brackets for building construction,or similar purposes, and the principal object is to provide as simpleand improved construction over that already known as possible, and onethat when placed in position on the side of a building can not readilybe jarred loose or removed without the removal of the scaffold.

Another obj ect is to provide such a bracket to which a railing may bequickly applied or removed therefrom.

Still another object is to provide novel means whereby the bracingmember of such a bracket will be prevented from penetrating beyondreasonable limits the object to which it is applied` Other objects andadvantages of the peculiar structure will appear in the furtherdescription of the invention.

Referring now to the accompanying drawing forming part of thisapplication:

Figure 1 is a perspective view of one of the improved brackets as itwould appear applied to a vertical wall;

Figure 2 is an enlarged view of the nail engaging end of the scaffoldsupporting members; and

Figure 3 is another illustration of the nail engaging end of thescaffold supporting members.

1 represents the bracing member of the bracket which is preferablyconstructed of a piece of hollow tubing or pipe, slightly curved andsharpened at its lowermost end as at 2, and curved in a like directionas at 3 at its uppermost end so as to normally proj ect vertically whenthe bracket is in use.

Just below the curve 8 in the bracket is attached as by a through bolt4, though somewhat loosely, the angle iron scaffold supporting bars 5,one side of each angle being cut away upon their free ends and theopposite side bent upwardly as at 6 forming an L-shaped terminal inwhich is formed an elongated slot 7, part of which is in the upturnedportion 6 and the other `part in the horizontal portion of each bar, andwhich klatter terminal is enlarged as at 8 so as to freely fit over thehead 9 of a common spike or large nail l() which is first driven intothe wall upon which the bracket is to be placed.

By this means it is obvious that the bracket must be placed upon thenails l0 it being assumed that there are two of such previouslypositioned in the wall for the purpose) by the members 5 being inoblique position as indicated in Figure 3 of the drawings. Then whenraised and drawn from the wall the nail heads will slip upwardly intothe slots 7 in the upturned portion 6 resulting in a hold which cannotbe released without the members 5 being again positioned as wheninitially applied.

The fiat sides of the members 5 being attached to the round member l asis obvious will permit of considerable lateral swinging motion thereofso that the spacing of the nails may not have to be accurate.

The lower end of the bracing member l is provided with a short piece ofangle iron l0. it being loosely attached thereto by a suitable bolt 11and is for the purpose` of preventing the sharpened point 2 of saidmember protruding too far into a hole or decayed piece of wood, or theground, when it may be desired to rest the lower end of the member lupon the ground.

Within the upper curved end of the member l is loosely placed a smallpiece of pipe 12. or rod if preferred, bent as shown with a U-shapedupper end into which a scaffold railing bar or scantling indicated at 13in dotted lines may be placed, thus forming a convenient rail for thescaffold.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

l. A scaffold bracket of the type described comprising a tubular bracingmember pointed at its lowermost end and curved upward` ly at theopposite end, two scaffold supporting members pivotally united uponopposite sides adjacent the upper curved end of the bracing member, saidsupporting members having nail engaging means at their opposite ends,and a removable goose neck rail supporting member within the upwardlycurved portion of the bracing member for the purpose described.

2. A bracket of the type describedcomprising a principal bracing member,a pair of angle iron supporting members pivotally attached npon oppositesides of the uppermost end or" the bracing member, each of said angleirons having an upwardly turned `free end and nail engaging slots Withinthe free ends of the supporting members, said slots being` so formed asto prohibit dislodgment of the supporting members from the nails in ahorizontal direction, they being removable only When the members are ina 10 substantially Vertical position.

In testimony Whereorn I hereunto aiiiX my signature in the presence oftwo Witnesses.
